On the hotel group's Facebook page, they just posted this announcement for the penny rooms, otherwise known as Tunedays:

We are delighted to announce that from 12.01am on Tuesday 13th July there will be 200 rooms available to book at our Westminster hotel for the cost of just one penny! The rooms will be available for reservations and will be allocated on a first come service. So make sure you have your fingers ready on the keyboard at midnight on Monday! Stay tuned for hints on which months these rooms are available!

Ahhh, that last line is key.

While the hotel is still opening on August 30, the penny rooms may be subject to blackout dates. We're guessing this is a lot like the Hoxton's £1 Sale where your best chances of getting the cheap room rate is to book a weekday stay months in advance.

There might be some other problems with the penny rooms promotion too. Several Facebook fans complained that the Tune Hotels website tends to stall or crash right around midnight making it impossible to even search for a penny room. However, one Facebook fan recommended waiting it out as he was able to find a penny room at 1:30am.

If you can't score a penny room, then how much can you expect to pay? Well, we selected a room at Tune Hotels for the dates of September 1 and 2 and found that rooms start at 90 GBP (for two nights) for a teeny tiny double room. Fortunately, it does have its own bathroom. Still, we've set our alarm clocks for Tuesday, July 13. Why pay full price when we could pay a penny?
